Collection of Loop Sentences of C and Detailed Explanation of Cases

There are many advantages in using loops-using loops can make the program realize judgment logic. With loops, you can take advantage of the powerful computing functions of computers. Below I list the loop statements in C #, and the code is as follows:

With the cyclic structure, it is beneficial to use the calculation

Loop statements in C #: while, for, foreach
1. while cycle

static void Main(string[] args)
{
 int[] hs = { 1,2,3,4,5,6,7,8,9};
 int ligh = hs.Length;
 while (ligh > 0)
 {
 Console.WriteLine(hs[ligh - 1]);
 ligh -= 1;
 }
 
 Console.ReadKey();
} 

2. for loop (for loop can be nested, for example, it will be used when doing bubble sorting)

static void Main(string[] args)
{
 int[] hs = { 1,2,3,4,5,6,7,8,9};
 // Flashback printing only needs to be modified 1 It can be judged under the following conditions 
 for (int i = 0; i < hs.Length; i++)
 {
 Console.WriteLine(hs[i].ToString());
 }
 
 Console.ReadKey();
} 

3. foreach loops through the elements in the collection (this writing seems to be unique to. NET)

static void Main(string[] args)
{
 int[] hs = { 1,2,3,4,5,6,7,8,9};
 // It's used here var Keyword, anonymous type ( Automatically inferred by the compiler ) You can replace it with int
 foreach (var item in hs)
 {
 Console.WriteLine(item.ToString());
 }
 
 Console.ReadKey();
}

for Loop Example

C # for Loop 1 is generally used in counting or sorting, which is equivalent to numbering each row of data. Therefore, the C # for loop plays an extremely important role in the development process.

int i; 
for(i=1;i<=10;++i) 
{ 
  Console.WriteLine("{0}",i); 
} 

The counter variable is an integer i, which starts at 1 and increments by 1 at the end of each loop. During each loop, the value of i is written to the console.
Note that when the value of i is 11, the code behind the loop is executed. This is because at the end of the loop where i is equal to 10, i is incremented to 11. This is in the test condition i < = 10, when the loop ends.

Finally, note that you can rewrite the above code by declaring the counter variable as part 1 of the C # for loop statement, as follows:

for(int i=1;i<=10;++i) 
{ 
  Console.WriteLine("{0}",i); 
} 

The above content is combined with C # language to achieve the basic cycle statement and combined with case introduction, friends in need can refer to it, I hope you support me a lot.
